The key reason Wasabi mixes have been so problematic for users is that their broken implementation creates proximity to known blacklisted UTXOs via their peeling problems.

Those don't exist for Samourai so either they block you for seeking privacy (most won't) or they let it fly because there is no proximity to blacklisted funds.

Since CoinJoin is overt on chain, I wonder if the certain services are more or less represented because of KYC-free culture, or just based on their volumes, or something else

More here as well, but notice the almost complete dearth of Samourai instances of flagging *because it actually works*:

Noob question: Is it a good idea to consolidate a bunch of UTXO's, or not?

Seth's right.

There's good record on CoinJoin flagging here: too https://6102bitcoin.com/coinjoin-flagging/
